Abstract

An approach to elasto‐plastic analysis of engineering structures is presented in this study. Simple plane truss finite element with two nodes is used. This element is ideally suited as a basis for studying plasticity theory since it implies one ‐ dimensional state of stress and strain. Material model of linear isotropic hardening is applied. Algorithm well ‐ known in literature is implemented in software package Wolfram Mathematica. Obtained results fully correspond with those obtained from commercial software packages. Developed code is open‐sourced and it is freely available for educational purposes.
